+--  This package contains the low level, operating system routines used only
+--  in the GNAT binder for command line processing and file input output.
+
+package Osint.B is
+
+   function More_Lib_Files return Boolean;
+   --  Indicates whether more library information files remain to be processed.
+   --  Returns False right away if no source files, or if all source files
+   --  have been processed.
+
+   function Next_Main_Lib_File return File_Name_Type;
+   --  This function returns the name of the next library info file specified
+   --  on the command line. It is an error to call Next_Main_Lib_File if no
+   --  more library information files exist (i.e. Next_Main_Lib_File may be
+   --  called only if a previous call to More_Lib_Files returned True). This
+   --  name is the simple name, excluding any directory information.

+   -- Binder Output --
+   -------------------
+
+   --  These routines are used by the binder to generate the Ada source files
+   --  containing the binder output. The format of these files is described in
+   --  package Bindgen.

+   procedure Create_Binder_Output
+     (Output_File_Name : String;
+      Typ              : Character;

+   --  Creates the binder output file. Typ is one of
+   --    'b'   create body file for case of generating Ada
+   --    's'   create spec file for case of generating Ada
+   --
+   --  If Output_File_Name is null, then a default name is used based on
+   --  the name of the most recently accessed main source file name. If
+   --  Output_File_Name is non-null then it is the full path name of the
+   --  file to be output (in the case of Ada, it must have an extension
+   --  of adb, and the spec file is created by changing the last character
+   --  from b to s. On return, Bfile also contains the Name_Id for the
+   --  generated file name.
+
+   procedure Write_Binder_Info (Info : String);
+   --  Writes the contents of the referenced string to the binder output file
+   --  created by a previous call to Create_Binder_Output. Info represents a
+   --  single line in the file, but does not contain any line termination
+   --  characters. The implementation of Write_Binder_Info is responsible
+   --  for adding necessary end of line and end of file control characters
+   --  as required by the operating system.
+
+   procedure Close_Binder_Output;
+   --  Closes the file created by Create_Binder_Output, flushing any
+   --  buffers etc. from writes by Write_Binder_Info.
+
+   procedure Set_Current_File_Name_Index (To : Int);
+   --  Set value of Current_File_Name_Index (in private part of Osint) to To
